Chemical selector
The Pesticide Selector includes suggestions for chemical control of pests in Kansas crops, which are provided by K-State Research and Extension, and may not be relevant for states other than Kansas. We will continue to expand this tool for help in selecting other types of agricultural chemicals, and for other states. Contact the myFields Team if you are interested in contributing content!

Crop type: Sorghum
Application type: Preplant or Preemergence
Lumax EZ is a premix of 2.49 lb S-metolachlor (Dual II Magnum), 0.249 lb mesotrione (Callisto), and 0.935 lb atrazine (a restricted-use pesticide). Lumax EZ can be applied preplant nonincorporated (up to 21 days before planting) up through planting but prior to sorghum emergence. Plant Concep-treated seed only. Applying Lumax EZ less than 7 days before planting will increase the risk of crop injury. Lumax EZ also may be applied as a split application to grain sorghum. Apply Lumax EZ at 1.35 qt/a as a nonincorporated early preplant application (7 to 21 days before planting) followed by a second application of 1.35 qt/a preemergence prior to sorghum emergence. The total amount of Lumax EZ cannot exceed 2.7 qt/acre. Do not apply to sandy soils (sand, sandy loam, or loamy sand). Do not apply to emerged grain sorghum. Do not use on forage sorghum, sweet sorghum, sudangrass, or any dual-purpose sorghum.
